Ace, Jessica Simpson and Eric Johnson
On June 30th, Simpson, 33, had her second child with former NFL star Johnson. She revealed to US magazine that it wasn't easy for her. "Pregnancy is a lot. It was hard to do two so close together." Just seven months after she gave birth to her first child, daughter Maxwell, she announced she was pregnant again. Even after having two children together, the couple is still not married. Simpson blames that on her fiance, telling Jay Leno, "We've had two different wedding dates, but he keeps knocking me up. We're doing it very backwards, I know."
